All objects under api/ and examples/api/ directories are selected by CONFIG_API. So we can move CONFIG_API switch to the top Makefile. In order to use CONFIG_API, the definition of SUBDIR_EXAMPLES-y must be moved after "sinlude $(obj)include/autoconf.mk". Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
